Application filed Ma 22j;1915. Serial No. 29,860;

Toall whom it may concern:

Be'it known that wen-Lows SCHWARZ and ROBERT VVnBnR, citizens of the United States,

residing at, QhehaIis, in the; county of Eewi's and Stateof Washington, haveinv ented: certain new and useful Improvements in" Sash- Locks, of which'ithe following'is a specification, reference being had" to the accompanying drawings.

This invention relates to an improved sash lock and" has for'its primaryobjecti to provide a device of thischaracterwhich' is par-' ticularly designed for use upon: French or casement windows wherein a or pivoted sash is employed; 9

One of'the more particular objects of the invention is to provide a device of the" above character which automatically operates to lock or hold the swinging sash at various angles with respect'to the frame within which it is mounted.

The invention has for a further general object to provide a sash lock o'f'the" above type which is applicable to, various window constructions having a pivoted sash without necessitating any alterations in the construction thereof and which may be readily adjusted to assure the positive action thereof in accordance with the weight of the swinging sash or peculiar existing conditions.

With the above and other objects in view, our invention consists in the novel features of construction, combination, and arrangement of parts to be hereinafter more fully described, claimed, and illustrated in the accompanying drawing, in which,

Figure 1 is a perspective view illustrating our invention applied to a familiar type of French or casement window, the sash being in a partly open position; Fig. 2 is a section taken on the line 2 2 of Fig. 1; Fig. 3 is an enlarged vertical section taken on the line 33 of .Fig. 2; Fig. 4: is a detail perspective view of the locking rod. Fig. 5 is an enlarged detail section showing the means for locking the rod against movement.

Referring in detail to the drawing, 5 designates the window frame and 6 the swinging sash which is pivoted or hingedly mounted upon one side of said frame, as shown at 7 Upon the inner face of the top rail of the sash, a bracket member 8 is secured, and said member has an angularly disposed lug 9 on one end provided with an opening 10 therein.

of the frame 5, the casing or sleeve 11 is mounted", said sleeve being provided with attaching flanges 12 which are apertured to receive suitable fastening screws indicated at13l Upon the upper end of the sleeve 11,

a substantially semircircular flange or plate 145 is; formed, the upper face of which is pro vided with a plurality of spaced notches or grooves 15therein.

16 designates generally the locking rod which is provided with an angularly disposed end portion 17 having a threaded terminal' 18. This angular end of the locking rod is loosely disposed through the bore of the sleeve 11 and the threaded terminal thereof projects below said sleeve. Within the sleeve 11,'the coil spring 19 is arranged up'on the angular end of the locking rod, the upper end of said spring bearing against a shoulder or seat 20. A thimble 21 is loosely disposed uponthe threaded terminal 18 of the locking rod and extends into the lower end of the sleeve 11, said thimble providing a seat for the lower end of the spring 19. A nut 22. is engaged upon the threaded end 18 of the locking rod and is adapted to be adjusted thereon to force the thimble 21 upwardly into the sleeve 11 against the action of the spring 19. In this manner, it will be understood that the tension of the spring 19 may be adjusted or regulated, as circumstances may require.

The longer arm or body portion of the locking rod is loosely disposed through the opening 10 in the ear or lug 9 of the bracket member which is secured to the window sash. This relatively long arm of the looking rod is provided upon its under side and adjacent to the angular arm or end portion 16 thereof with a single beveled tooth 23 which is adapted to seat in the recesses or notches 15 provided upon the face of the plate 14.

From the above description, the manner of operation of the device will be readily understood. When the window sash 6 is swung outwardly from the frame at an angle with respect thereto to dispose said sash in a partly open position, the angular end 16 of the locking rod turns in the sleeve 11, the longer arm of said rod sliding through the apertured bracket lug 9. The tooth 23 on the locking rod rides over the ridges between the notches or recesses 15 in the plate 14 against the action of the spring 19. This spring acts to force the angular end of the locking'rod downwardly into the sleeve and hold the tooth in one of the notches 23, whereby the sash is locked or held in its partially open position, so that said sash will not be swung by high winds and slammed against the frame of the window. The tension of the spring 19 may be readily regulated by simply turning the nut 22 in the manner above stated.

From the foregoing, it will be seen that We have produced a very simple, effective and serviceable sash holder or lock which does not require any manual manipulation in order to retain the sash in its partially open position; but when the swinging of the sash ceases, the lock immediately acts to retain the sash in such position and prevent the further movement thereof.

It is obvious that our improved locking device may be applied to either side of the window frame, and may also be used when the sash is hinged or pivoted at its top or bottom for vertical swinging movement It is also to be understood that our in vention is susceptible of considerable modification in the form, proportion and arrangement of the several detail features thereof and we, therefore, reserve the privilege of resorting to all such legitimate changes as may be fairly embodied within the spirit and scope of the invention as claimed.

the locking rodis slidably' engaged, said angulararm extending beyond one end of ,the sleeve, a thimble engaged in the latter end ofthe sleeve,a spring arranged in the sleeve and hearing at one of its ends against said thimble, said locking-rodhaving a tooth thereon for engagement in the notches of saidplate under the action of said spring,

whereby the-sash is held against swinging movement, and, a' nut engaged upon the threaded terminal of the arm on the locking and cooperating with said thimble to regulate the tension of said spring.

In testimony whereof we hereunto afiix our slgnatures in the presence'of two 'wltnesses. I v v LOUIS SOHWARZ.
